Specification of Letters Patent.

Patented Jan. 15, 1907.

Application filed July 5,1906. Serial No. 324,902.

To (5H LII/bull) it may concern:

Be it known that l, WiLLnin Sonwuxwn- BER, a citizen of the United States, residing at Seattle, in the county of King and State of vvashington, have invented certain new and useful improvements in Ventilators, of which. the following is a specification, reference being had therein to the accompanying drawings, in which Figure 1 is a front elevation, partly brolten away, of a device ei'nbodying my invention and shown attached to the lower rail of a wimlow-sash; Fig. 2, an outside elevation of the sash-rail with the toraminous covering plate thereon; Figs. 3 and A, horizontal and Vertical sections taken through lines 3 3 and et 4, respectively, of Fig. l.

The invention relates to ventilators, and specitically to an improvement in the ventilator shown and described in United States Patent No. 5-l2,i\37, issued to me July 16, i595; and the object of the improvement is to perfect the same by rendering it more elli cient in operation, while simplifying the construction and reducing the cost of manufacture.

\Yith this in view the invention consists in the peculiar at'laptation and combination of parts, which will be describml hereinafter with reference to the said drawings.

The invention comprises aeasing which is adapted to be secured, as by screws 5,.to the inside of the bottom rail R of a window-sash or in other suitable places, and for convenience in manufacturing is desirably made of two parts which are rigidly secured to each other by fastenings, such as by screws 6. One of these casing parts 7 is in the form of a plate with a depression or cavity ts at its rear which extends almost the entire length thereof and has an opening 9 of lesser length, while the other part it) is formed to' protruoe forwardly and is open at the back to make coinn unication betweenihe opening 5) and an opening it at the top, which directs the "fresh entering air in an npwanly cirectien. The casing part it) is formed with a concave lower portion to provide a shoulder 12 to furnish a linger-gripping surface, whereby when the thumbs are caught over the top edge 13 of the part the window-sash may be most conveniently raised or lowered; .1

Positioned at the front of them Jity S and of less length than the same isfla thin sheet of metal 14, which willbe hereinafter denominoted as the shutter and is provided with a handle 15, with which it is moved by fingerpressure from side to side, as desired, to cause the apertures 16 thereof to register with correspondingly-disposeil apertures 17 of a stationary partition-plate 18 when the sluitter is brought to the extreme end of its travel in one direction or be masked by the imperferate port ions thereof when moved to the opposite end of its travel. The partition-plate is of a length slightly less than the said cavity in which it is positioned and is rigidly held against the shutter and the latter against the marginal edges 19 of the casing part 7 by a spring 20, which is connected to the partition centrally of'its length by a rivet 21. This spring also serves to press a screen 22, preferably of wire-gauze, against the opposing face of the sash-rail it and leave a space 23 intervening the gauze and the partition for the more perfect distribution of the air to the various apertures of the latter. The ends of the gauze and the two said plates are retained in the ends of the easing-cavity by spring-metal plate 24, provided at and secured to each end of the part 7, thus enabling all of the aforedeseribed members of the device being retained together as a single piece and in their proper relations and making it convenient for attachnnnit to the-window.

The sash-rail R is bored with a number of holes 1', having their axes desirably inclined downward toward the outside and are com municatively connected at their outer ends by a horizontally-arranged channel 1", as shown in Figs 3 and i. A perforated late 25 is preferably employed to cover the oles of the sash-rail at the outside in order to improve the appearance when viewed from that direction.

The advantages of the present invention reside principally in the simplicity of the device and the suitability of the various parts to their respective ofiices. The air is free to enter a room in direct lines and thence diverted upwardly to create the proper current for etfective ventilation, and while the,

shutter and the fixed partition make a nice working iit with each other the auze is so! deflected as to permit the air to freely be admitted to all of the plateaperturcs from any of the rail-holes. l 'urthermore, bythe em ployment of the channel connections between the holes in the rails fewer are required and of less size than would otherwise be necessitated to furnish sutlicien't conduits for the air, thereby allowing not only of the apps .i still l'nrther advantage is trallv of their lcnt'tlnand respectivelypressing them against; the aslnrtnl and the shut- I casing ha vine a recess at its hack and a for wardlyprojecting portioil open at its top and cotnnnniieativel connected with. said recess,
